Dougster: Yes sir, that is kerfed yellow pine. Got the idea from Super Dave's PH16; worked great!

The "white graphite" to my understanding, is applied the same way the regular black graphite is but I was looking for a white bottom. The actual name is Hexagonal Boron Nitride; once again information I got off this forum! Planning on applying directly over my pigmented epoxy, after a little more fairing (almost out of the woods). Only going to prime from the chines up.

Thanks. Didn't know about that but since I already have the graphite I guess I'll stick with it. I'll be interested in seeing your results.

Dustin,
Looks like the exact same motor I have on my P19, for most the same reasons, if your gonna just through that lower unit in the back of the garage throw it my way, shoot me a price. (what year is it)

Your build looks very nice!

Joe, I was planning on selling the lower unit for $1400; need some funds to help pay for the effort. The motor is either an '08 or '09, but it is straight out of the crate and even turned over.

Will, just trying to keep up with you. . . and by the way hadn't seen anything from you lately. C'mon man, I need you to stay ahead of me so I can see my next step!!

Been wrapping up a few loose ends to get ready to graphite the bottom:

Sanded the seal coat down with 120 grit

Then did some touch up fairing and prepped the hull for graphite:

Thinking I can just do a quick sand tomorrow and get the graphite done this weekend.

Couple of questions before I pin the ears back:
What is the correct ratio for graphite to epoxy? Different ratio per coat?
I read on here that using a heat gun will help the graphite "self-level" and reduce air bubbles. Am I interpreting correctly?

I'm not sure that a "correct" ratio has ever been established :lol: But I get best results with about 1/3 graphite to epoxy, by volume, not weight. 12 oz. epoxy, 4 oz graphite in a measuring cup.

Dustin, I hope to have something picture-worthy soon...

I used the heat gun on my third and final epoxy coat. I was impressed with how nicely it smoothed things out.

Did the first coat of white graphite on the bottom Friday afternoon, but it did not turn out as expected. Not sure where I went wrong. The entire coat has what appears to be a grit, like sandpaper.

I rolled it on and tipped the entire bottom. I used 3 ounces of graphite in 12 ounces of epoxy. Any ideas on what went wrong? Could it have been that the graphite did not "dissolve" completely in the epoxy?

I imagine you were sure to sift the graphite and mix it well. I don't have any suggestions for you but if nothing pops up in this thread you may want to PM Casey (flyfishingmonk) and ask him. I have seen his hull and the white stuff was slick, flat, not gritty.
